Publication number is 2751746, Granted publication day is that the Chinese utility model patent document on January 18th, 2006 discloses a kind of filling type intestinal pressure catheter, it comprises the catheter body of top closure, independently be provided with four fluid injection tracts and an inflation tract in the catheter body, have a pressure tap separately on the described fluid injection tract, have an air-filled pore on the described inflation tract.Wherein: the pressure tap position of the first fluid injection tract is corresponding to the sigmoid colon section of intestinal, the pressure tap position of the second fluid injection tract is corresponding to the rectum section, three, the pressure tap position of the 4th fluid injection tract is corresponding to anal canal internal sphincter section, and four pressure taps all are opened in first position, circular section of catheter body.The air-filled pore position of described inflation tract is between the pressure tap of the pressure tap of the first fluid injection tract and the second fluid injection tract, and the catheter body of the described air-filled pore position outside is enclosed with air bag.The tail end of catheter body is respectively equipped with the fluid injection that links to each other with described fluid injection tract and prolongs pipe and the inflation prolongation pipe that links to each other with described inflation tract.It has check point darker wider, detect characteristics such as accuracy rate is higher.But, though technique scheme can be tested the pressure of different parts, but owing to be provided with a plurality of tracts in catheter body, and each tract sprains and respectively has a pressure tap, and the catheter body outside is enclosed with air bag, and the relation of the position between pressure tap and the air bag is not made specific description, experiment shows that pressure tap is too far away apart from air bag, and the venting quality in the air bag is bad, the data that test out can be subjected to very big influence, and test data is inaccurate.
The utility model content
For solving the problems of the technologies described above, the utility model proposes and a kind ofly can guarantee fully that venting quality is good in the air bag, test data is the rectum pressure catheter more accurately.
The technical solution adopted in the utility model is as follows:
A kind of rectum pressure catheter, the catheter body that comprises end sealing, be enclosed with the pressure measurement capsule on the blind end outer wall of catheter body, it is characterized in that: independently be provided with at least 2 single chamber arms in the described catheter body, the one end sealing of single chamber arm, at the other end of catheter body, each single chamber arm stretches out described catheter body and each self-separation, and the separating end of each single chamber arm is connected with interface respectively; Have a side opening on each single chamber arm in described pressure measurement capsule, the close pressure measurement capsule inner wall of wherein offering on any one single chamber arm of side opening from catheter body blind end that end far away, and between the side opening of offering on the arm of single chamber spacing is arranged.
The number of described single chamber arm is 2, is respectively A chamber arm and B chamber arm, is connected with A chamber joint on the arm of described A chamber, is connected with B chamber joint on the arm of described B chamber.
The close pressure measurement capsule inner wall from catheter body blind end that end far away of the side opening of offering on the arm of described A chamber, the side opening of offering on the arm of B chamber is near the blind end of described catheter body.
Described pressure measurement capsule is air bag or water pocket, and the pressure measurement medium in the described pressure measurement capsule is a water.
Be connected with pressure transducer or aerofluxus, perfusion pressure measurement medium on the described interface.
Advantage of the present utility model is:
1, because the close pressure measurement capsule inner wall of offering on wherein any one single chamber arm of the present utility model of side opening from catheter body blind end that end far away, and between the side opening of offering on the arm of single chamber spacing is arranged, when being full of pressure measurement medium (as water) in the pressure measurement capsule, side opening on each single chamber arm since between be separated with distance, there is not corresponding setting between side opening and the side opening, the water of single chamber arm and air bag inside can form circulation, flow, can discharge the bubble of the medium that is positioned at pressure measurement capsule any position very easily, venting quality is good, and the data that obtain during test internal rectum pressure are just more accurate.
2, this utility model novel, simple in structure, can satisfy simultaneously that pressure-flow rate is measured synchronously and filling period bladder pressure measure process is pressed (abdominal pressure) to rectum mensuration, reach international urine and control the stipulative definition that association's urodynamics is measured, pressure-measuring pipe is easily processed, and easily uses.
